Infrastructure Security in AWS App Studio
As a managed service, AWS App Studio is protected by the AWS global network security
procedures that are described in the Amazon Web Services: Overview of Security Processes
You use AWS published API calls to access App Studio through the network. Clients must support at least Transport Layer Security (TLS) 1.2, but TLS 1.3 is recommended. Clients must also support cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.
Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
